seed
"The devil's weed
(datura inoxia or Jimson weed)
is like a woman, and like a woman she flatters men.
She sets traps for them at every turn.
I warn you against it. There are many paths.
It is useless to waste your life on one path,
specially if that path has no heart."
"But how do you know when
a path has no heart, don Juan?"
"Before you embark on it you ask the question:
Does this path have a heart?
The trouble is nobody asks the question;
and when a man finally realizes
that he has taken a path without a heart,
the path is ready to kill him.
At that point very few men can stop
to deliberate, and leave the path."
